xov xwm

Txawm hais tias HDPE ob-phab ntsa hauv qab thiab PVC ob phab ntsa bellows yog hu ua ob-phab ntsa hauv qab, tab sis ntxiv rau qhov zoo li me ntsis zoo sib xws, nyob rau ntau qhov chaw lawv txawv heev, yog tias koj tsis ntseeg nws, tsuas yog saib ntawm me series rau koj sau cov txawv nws.

I. UPVC ob phab ntsa hauv qab

UPVC ob-phab ntsa hauv qab, tseem hu ua PVC-U ob-phab ntsa hauv qab, yog cov yeeb nkab tshwj xeeb nrog cov phab ntsa zoo nkauj, corrugated sab nrauv phab ntsa thiab hollow sab hauv thiab sab nrauv phab ntsa ua tiav thiab tsim los ntawm polyvinyl chloride ua cov khoom siv tseem ceeb.Cov yeeb nkab muaj qhov zoo nkauj zoo nkauj, cov qauv tshwj xeeb, lub zog siab, du sab hauv phab ntsa, kev sib txhuam me me, kev ncig loj, lub hauv paus tsis tas yuav ua lub hauv paus pob zeb, lub teeb yuag, yooj yim tuav thiab txhim kho, kev tsim kho sai;Roj hmab nplhaib socket kev twb kev txuas, txhim khu kev qha txoj kev, yooj yim los xyuas kom meej kev tsim kho zoo;Yooj yim interface.Muaj zog tiv thaiv tsis sib xws;Zoo toughness, corrosion kuj mus rau ntau yam tshuaj lom neeg tawm;Tsis muaj nplai nyob rau hauv cov yeeb nkab, qhov yooj yim yuav tsum tsis txhob dredge, faus kev pab cuam lub neej ntawm ntau tshaj 50 xyoo.

Lub cev muaj zog

Kev ntsuas kev sib txuas tsis tawg, tsis muaj qhov cuam tshuam rau kev sim TIR≤10% lub nplhaib nruj S1≥4KN / ㎡, S2≥8KN / ㎡ lub nplhaib yooj yooj yim tsis tawg, ob phab ntsa tsis tuaj tawm qhov cub kuaj yam tsis muaj kev sib cais, tawg, npuas Manning roughness coefficient n = 0.010.

2, HDPE ob phab ntsa corrugated yeeb nkab

HDPE ob-phab ntsa corrugated yeeb nkab, tseem hu ua polyethylene ob-phab ntsa corrugated yeeb nkab, yog ib hom tshiab ntawm lub teeb yuag yeeb nkab ua los ntawmhigh-density polyethylene.Nws muaj cov yam ntxwv ntawm lub teeb yuag, kev kub siab tsis kam, zoo toughness, ceev kev tsim kho thiab lub neej ntev, thiab lwm yam. Nws zoo heev phab ntsa qauv tsim zoo heev txo tus nqi piv nrog rau lwm cov qauv ntawm cov kav dej.Thiab vim hais tias kev sib txuas yog yooj yim thiab txhim khu kev qha, nws tau siv dav hauv tsev thiab txawv teb chaws.Muaj ntau qhov hloov cov yeeb nkab thiab cam khwb cia hlau yeeb nkab.Cov yam ntxwv ntawm kev ua haujlwm:

HDPE ob phab ntsa corrugated yeeb nkab muaj tshuaj lom neeg ruaj khov, kev laus ua haujlwm thiab ib puag ncig kev ntxhov siab tawg ua haujlwm.Lub HDPE ob-phab ntsa tshuab ua los ntawm nws cov ntaub ntawv raw yog nyob rau hauv cov yeeb nkab hloov tau.Nws cov khoom yog raws li nram no:

Muaj zog tsis kam mus rau sab nraud siab: sab nrauv phab ntsa yog ib puag ncig corrugated qauv, uas zoo heev txhim khu lub nplhaib txhav ntawm cov yeeb nkab, yog li txhim kho qhov tsis kam ntawm cov yeeb nkab rau av load.Hauv qhov kev ua tau zoo no, HDPE ob-phab ntsa corrugated yeeb nkab muaj qhov pom tseeb zoo piv nrog lwm cov kav dej.Tus nqi qis engineering: nyob rau hauv cov xwm txheej ntawm xws li load, HDPE ob-phab ntsa corrugated yeeb nkab tsuas yog xav tau ib phab ntsa nyias kom tau raws li qhov yuav tsum tau ua.Yog li, piv nrog cov khoom phab ntsa ntawm cov khoom siv tib yam, nws tuaj yeem txuag tau li ntawm ib nrab ntawm cov khoom siv raw, yog li tus nqi ntawm HDPE ob-phab ntsa corrugated yeeb nkab kuj tseem tsawg.Qhov no yog lwm qhov tseem ceeb ntawm cov yeeb nkab.

Kev tsim kho yooj yim: Vim tias lub teeb yuag ntawm HDPE ob-phab ntsa corrugated yeeb nkab, kev tuav thiab kev sib txuas yog yooj yim heev, yog li kev tsim kho sai thiab kev saib xyuas yooj yim.Nyob rau hauv cov xwm txheej ntawm lub sijhawm siv nruj thiab kev tsim kho tsis zoo, nws qhov zoo yog pom tseeb dua.Zoo tsis kub tsis kam, cuam tshuam tsis kam: lub embrittlement kub ntawm HDPE ob phab ntsa bellows yog -70 ℃.Cov xwm txheej kub tsis tshua muaj siab (siab dua -30 ℃) tsis tas yuav siv cov kev tiv thaiv tshwj xeeb thaum tsim kho, kev tsim kho lub caij ntuj no yooj yim, thiab HDPE ob phab ntsa corrugated yeeb nkab muaj kev cuam tshuam zoo.

Kev ruaj ntseg tshuaj zoo: Vim tias HDPE molecule tsis muaj polarity, nws muaj tshuaj lom neeg zoo heev.Tsuas yog qee qhov muaj zog oxidants, feem ntau cov tshuaj lom neeg tsis tuaj yeem rhuav tshem nws.Av, hluav taws xob, cov kua qaub thiab cov hauv paus ntsiab lus nyob rau hauv kev siv ib puag ncig yuav tsis ua puas lub kav dej, tsis muaj kab mob, tsis muaj scaling, nws ncig cheeb tsam yuav tsis txo nrog rau lub sij hawm khiav.

Lub neej ua haujlwm ntev:

Nyob rau hauv qhov xwm txheej tsis muaj hnub ci ultraviolet, HDPE ob chav phab ntsa tshuab tuaj yeem siv rau ntau tshaj 50 xyoo.Ib qho ntev ntawm HDPE ob-phab ntsa corrugated yeeb nkab axial tuaj yeem ua tau me ntsis flexural, tsis cuam tshuam los ntawm qee qhov kev sib haum xeeb ntawm qhov tsis sib xws, tuaj yeem tso ncaj qha rau hauv ib qho me ntsis tsis ncaj zawj thiab lwm yam.Qhov zoo:

1, cov qauv tshwj xeeb, siab zog, cuam tshuam tsis kam compression, phab ntsa yog du, kev sib txhuam loj dhau lawm;Kev sib txuas lus yooj yim sib koom ua ke, tsis muaj to.

2, lub teeb yuag, kev tsim kho ceev ceev, kev ua haujlwm qis, tus nqi qis dua.

3, polyethylene hydrocarbon polymer molecules nyob rau hauv tsis tshua muaj acidic thiab alkaline faus lub neej rau ntau tshaj 5 xyoo, thiab yog ntsuab, non-toxic, non-corrosive, tsis muaj scaling.

4, lub teeb yuag, kev tsim kho sai, txo cov nqi.

5, faus kev pab cuam lub neej ntau tshaj 50 xyoo.

Txawm hais tias nws yog ib khub menyuam ntxaib, txawm hais tias lawv zoo sib xws hauv txhua txoj hauv kev, cov niam txiv yuav paub, yog tias ob lub phab ntsa ob lub qhov khoob no tsis yog menyuam ntxaib, nws yog ib qho kev qhia yooj yim, thiab yog tias peb paub txaus txog lawv. , peb ua tau.
